Neat utility to convert uppercase filenames

[Rahul Dhesi]

I think all the programs posted so far have the bug that if you have
files called "x" and "X", they will delete one of them.  Here's mine.
Doesn't disturb files whose names already contain any lowercase
characters (thus preserving names like "Makefile"), and even has online
help!  Not shar'd, cut out and use.

#! /bin/sh
# converts to lowercase
if test $# -lt 1; then
   echo "usage: lfname file ..."
   echo "(specified filenames are converted to lowercase)"
   exit 1
fi

for f in "$@"
do
   case "$f" in
   *[a-z]*)
      #echo "skipping $f, contains lowercase chars"
      ;;
   *)
      newname=`echo "$f" | tr 'A-Z' 'a-z'`
      if test "$newname" != "$f"
      then
	 if test -f "$newname"
	 then
	    echo "$newname already exists"
	 else
	    mv "$f" "$newname"
	 fi
      fi
      ;;
   esac
done
exit 0
